A doctor specialising in addiction has called on Fianna Fail to confirm where it stands on drug-reduction policy after a post on the party's social media caused outrage.

The main opposition party was forced to delete an official Facebook post criticising the Government's drug reduction policy.

The post, which highlighted recent hospital waiting figures, read: "Let me get this straight. There are 1,000,000 (that's one million folks) on the waiting lists and the HSE are running campaigns like this? Perhaps HSE Ireland #YouAreOnCrack"

The post has been widely criticised by drug treatment charities and rival politicians as cruel and misinformed.

Labour Senator Aodhan O Riordain has called on Fianna Fail leader Micheal Martin to apologise for the post, calling it "degrading and deliberately divisive".
